🌍 Global Cooling: Would you support it… even temporarily?

🌡️ The world’s leaders just reaffirmed their commitment to 1.5 degrees of global warming. With less than 6 years of carbon budgets left, this feels like a lofty goal to many. Even 2 degrees feels out of reach given current trajectories.

Broadly speaking, humanity has three options to prevent climate catastrophe:

1️⃣ Reduce emissions

2️⃣ Remove emissions

3️⃣ Global cooling interventions

🏭 Before the 2018 IPCC 1.5°C report, most people and governments thought we could just reduce emissions. Now we know it won’t be enough. There is a growing recognition we will need to remove emissions (carbon dioxide removal) both for residual and historical emissions.

❄️ Increasingly, a third option is getting increasing attention: resort to more drastic interventions such as solar radiation modification (SRM) - including stratospheric aerosol injections (SAI) or marine cloud brightening (MCB) - to actively reduce temperatures: global cooling.

⌛ Advocates argue that we have run out of time to focus on reducing and removing only. If we do not intervene now, we will reach irreversible global tipping points that will create uncontrollable warming spirals.

🤷 This is pretty controversial, as we simply do not know how a complex ecosystem like planet earth will react when global cooling is done at scale. Nor do we know how to govern global cooling.

🤔 Whether we support it or not, global cooling is increasingly part of the climate conversation and ignoring it won’t make it go away. So we are going to tackle it head on instead.
